摘要
采用受污染河水对菌藻生物膜系统进行培养驯化,在水深为0.4m,停留时间为6h,温度和光照适宜的条件下5d即可培养成功。培养成熟时优势菌属为裸藻属(Euglena)、栅藻属(Scenedesmus),藻类计数为1.01×104 CFU/mL,且对COD、NH3—N的去除率分别为57%、80%。研究发现,菌藻生物膜系统培养简单、启动快,适合在小城镇或农村地区推广应用。
The Algae-bacteria symbiosis system was cultivated directly in the polluted river under 0.4 m water deep,6 h retention and good weather conditions.After about 5 days cultivation,algae-bacteria symbiosis system is dominated by Euglen and Scenedesmus.The removal rate of COD and NH3—N is 57% and 80% respectively.The algae-bacteria symbiosis system is simple and the startup is quick.Both are good for the application in Small towns and rural area.
